Differentiated Instruction: How to Reach Every Student in Class

Every class is mixed-ability — that's not the exception, it's the rule. High achievers want more depth; others need time to consolidate the basics. Differentiated instruction is the attempt to meet both needs without essentially running two parallel lessons.

This article introduces practical strategies that don't require triple the preparation time.

Why differentiation often fails

ℹ️

The biggest obstacle isn't the method — it's the assumption. Many teachers equate differentiation with more work, and so they abandon it before it starts.

Good differentiation doesn't mean creating a separate worksheet for every student. It means designing tasks with a structure that allows different learners to reach the same goal by different routes.

1. Tiered tasks — one foundation, three levels

Exploration15–20 min.

The most practical day-to-day method is the tiered task. All students work on the same topic — but with tasks scaled to different levels of demand.

A simple three-tier model:

Foundation: gap-fills, multiple choice, pre-structured tables — focus on understanding core concepts
Standard: open-ended tasks requiring transfer and written explanation in own words
Extension: problem-based tasks, cross-topic connections, creative application

Example — Biology (Grade 9): Topic: photosynthesis.

Foundation: Label a diagram of the light reaction using a word bank.
Standard: Explain the difference between the light-dependent and light-independent reactions in your own words.
Extension: Why does biomass production slow down on overcast days? Use the photosynthesis equation in your explanation.

2. Choice tasks — building ownership

An often-overlooked approach: let students choose which tasks they tackle. This works well when there's a compulsory core and voluntary extension options beyond it.

Why it works: Autonomy increases motivation. Students who choose their tasks work with more persistence.

Example — English (Grade 8): After a unit on the Simple Past, four tasks are available. Students must complete any two. One task is significantly more demanding and earns a bonus marker.

💡

Be transparent about which tasks target which level. "This is for everyone" — "This is for everyone who wants more" — without stigma.

3. Using grouping strategically

Practice8–15 min.

Differentiation also happens through grouping — not just task design.

Ability-grouped tables: homogeneous groups can receive targeted support without others waiting
Mixed-ability pairs: stronger students explain — which consolidates their own understanding; weaker students receive peer explanations at eye level
Station work: each station has a defined difficulty level; students move through them at their own pace

What to avoid: making ability groups permanent. Fixed groupings reinforce social hierarchies and become self-fulfilling.

4. Scaffolding — temporary supports

Scaffolding means equipping learners with supports they gradually set aside as confidence grows.

Practical scaffolding tools:

Word lists or glossaries provided alongside the task
Sentence starters as structural guides
A worked example for the first of three similar exercises
Graphic organisers (mind-map template, comparison table)

Important: scaffolding should be opt-in. Students who don't need it don't take it. Students who need it aren't forced to fail without it.

Building differentiation into your lesson plan

Differentiation needs to be embedded in planning — ideally from the moment you define your learning objectives.

Questions that help during planning:

What must every student achieve as a minimum?
What can high achievers tackle in addition — and how do I prepare for that?
At which points in the lesson do I need the most flexibility?
